Split-brain scenarios can be resolved using an odd number of nodes (or voters) to achieve a majority consensus to agree on the state of the system, stopping the services on the minority side to prevent conflicting operations. Once communication is restored, the stopped nodes can rejoin the cluster and synchronize their data. Vector clocks are a great abstraction for ensuring correct ordering as well.
